Product description
The TREL-8 Low Temperature Remote Probe Logger measures and stores up to 8000 temperature readings over -80°C to +40°C (-112°F to +104°F) measurement range from associated interchangeable LogTag® ST10 type remote probe temperature sensor (available in lengths up to 3 meters (9’10”).
It is intended for use in monitoring of articles stored at low temperatures such as in dry ice type environments. Using the LogTag® Interface Cradle and LogTag’s freely available companion software LogTag® Analyzer.

|
Sensor Measurement Range |
-80°C to +40°C (-112°F to +104°F). |
||
|
Operating Temperature Range |
-20°C to +40°C (-4°F to +104°F). |
||
|
Storage Temperature Range |
-10°C to +55°C (14°F to +131°F). |
||
|
Rated Temperature Reading Accuracy |
With the logger case sitting in an environmental temperature between 0°C and 50°C: Better than ±1°C for -30°C to +20°C. Better than ±1.2°C for -45°C to -30°C and +20°C to +40°C. Better than ±1.7°C for -80°C to -45°C. Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below. Accuracy figures can be improved by recalibration. |
||
|
Rated Temperature Reading Resolution |
Less than 0.1°C for -80°C to 0°C. Less than 0.2°C for 0°C to +20°C. Less than 0.5°C for +20°C to +40°C. Please see the Rated Native Resolution chart below. LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®. |
